Day name table

Like all FRC months Messidor lasted 30 days and was divided into three 10-day weeks called décades (decades). Every day had the name of an agricultural plant, except the 5th (Quintidi) and 10th day (Decadi) of every decade, which had the name of a domestic animal (Quintidi) or an agricultural tool (Decadi).
